I can do, but I think your missing the point. Its a free party. I'm doing it for free. I have been told this when I advertised a previous event and in the future if i'm advertising something I'll donate. The music side of this website is more niche then obviously bouldering, so is it worth paying £5 an one person comes to the night?? If I was advertising climbing holds, courses bouldering comps etc, then this is a direct audience. Techno on a bouldering site isn't. Isn't it better to have a website where people can add things advertise things and contribute and be part of a culture then an empty forum with no one visiting?
I respect someone puts a lot of time and effort into the site but its people contributing that make this site what it is.
